Establishment and application of assessment index system for river health:A case study in the Huntai River basin
摘要
Abstract
An index of land use, w ater and habitat quality ( ILWH Q) w as proposed and applied to evaluat e the environmental qualit y in the st udy area. The least deteriorat ed sites ( ILWH Q ≤ 2; T 13, T15, T16, T17 and T 18) were selected as the reference sites. Five of t he initial 35 candidate metrics w ere select ed using a stepw ise procedure ( principal component analysis, the analysis of the range of index value distribution, stepwise regression analysis, Pearson correlation) to evaluate metric stabilit y, respon-siveness to environmental variables and redundancy. The selected metrics included the number of Cyprinidae species ( F5) , the proportion of individuals as bent hic species ( F12) , the proportion of omnivore species ( F14) , the proportion of individuals as tolerant species ( F22) , and the proportion of demersal eggs species ( F23) . Ration scoring met hod was employed to score the five metrics, and the ecosystem health of the Huntai River basin defined into five classes. The results show ed that five sites were in excellent condition, eleven were in good condition, eight in normal condit ion, nine in poor condition, and eight in very poor condition in the T aizi River basin. There w as no site in excellent condition, five in good condition, six in normal condition, six in poor condition, and six in very poor condition in the H un River basin. T he sites in poor and very poor conditions accounted for 52. 2% of the total sites in the H un River basin, and 41. 5% of t he total sites in the T aizi River basin. These f indings indicated that ecosystem health was w orse in the Hun River than that in the T aizi River.关键词
